The invention relates moreA particularly to valves for the' control of edible fluids commonly known as sanitary valves.

In milk Pasteurization one of the com-` and emptiedthrough piping controlled by sanitary valves. It will be obvious that'any leakage or failure in'y these' valves'will permit the uncontrolled flow to or from the containerof a quantity of milk which has not been held for the required time at the necessary `temperature- Iffsuch leakage is permitted to pass into the-discharge line with the properly Pasteurized milk, the latter is in danger of reinocul'ation by the undestroy'ed bacteria in the milk which has es caped the prescribed treatment.

It is the principalv object of thisv inven- Etion to provide an improved sanitary valve fo'r controlling the filling and emptying of .Pasteurizingy holders, which is constructed to intercept andJ direct outwardly from the main passages any` leakage occurring-'in the valve whenf it is in closed positionf Other objects and advantages will be apparent in the. following'detailed description of a preferred embodiment of the'inventio'n which I have selected for illustration in the accompanying drawings. It,` will be understood, however, that'variou's changes in form,v construction and arrangement may be madeby those skilled in they art'withou't departing from the scope and spirit oi' the invention as expressed-in the appendedclaims. Referring to the drawings, Fig. 1 repre! sents a sectional elevation ofthe valve structure, the valve being illustrated in this'igure in opened position. 2. is asimilar sectional elevation with tlievalve parts illustrated in closed po'sitionl"y Fig. 3 is a cross sectional view taken on the planes .ofv the irregular line-3 3 in Fig. 2; Fig; itis a cross sectional view taken on the plane of the'line 4-4inFig-l. The numeral 1 indicates the bottom wall of a liquid holding container to whichfis suitably secured a'fiXture Q'having .anoutlet opening 3 passing therethrough. j Abuttmg the lixture 2 is a core memberlifpreferably removably secured the tintura means of at union nut 5 threaded upon a suitably l formedfportionfof the fixture 2" and engaging a flange 6 of'the'core. The core A4lis formed preferably with a tapered or conical outer contour.` The endk of the vcore adjacent the fixturev 2 is provided with a longitudinal inlet passage 7, in registerl with thel container 'outlet opening 3 fat its upper endand in -vcommunication at its lower end'A with a port opening 8 in the lateral periphery of the coijei VSp'aced from the port opening 8` afsecond port opening 9 which communicates with an outlet assage 10 extending longie tudinallythrough` the v-opposite end ofy the core, the l'atterbeing preferably provided at its lowerextremity with screwfthreads 1,1" for the 'attachmentof suitable piping. to receivef'thel discharved liquidi I -Mounted upon the core 4, in rotatable operative relation thereto,y is a rotatable 'casing linte'rnally forming a seatV for 'the coni? cally vformed; core 4 4and controllingV .the two port openings 8 and '9, The. casing A12 is retained-1 in l'seated relation to the core 4', Preferably byfmleans ofk acoiled kspring '13 bejaingupon the' lwei" end 0f. the Casing. and outwardly supported by means of an annular abutmentl "14y threaded; upon the lower end of the core. The casingmay be rotated upontlieI core by means offa' handle 25.,

,The casingl12 is provided with a lateral chamber l5whichf opens upon 'the' core t andis, of' sufficient dimensions toun'covei; both of thepot 'openings and.k 9; when positioned'thereover. The chamber l15y functionsv to open communication between the ports 8 and 9l for the flow therethrough of liquid from the inlet passage? to theoutlet passage l0.rv The lower: Wall of the chamber 1.5 is

provided with. an'auxiliary outletr opening 16 leadingmoutwardly of the casing indef- Pendenflyofth@ normal valvepassasss The auxiliaryV outlet opening 1 6 is yc ontrloll,ed by a'valve 1 7 carried by the longitudinallyy grooved'. stem 18 having'fguiding bearing in rtheauxiliary outlet passage.r The stem 18 ioo the stem is "adapted to be engaged by a 22 carried by theretaining washer 14, the cam being oi' such form and in such position that with the operative rotation of the valve easing 12 to swing the chamber 15 out of register with the port openings 8 and 9, the" auxiliary outlet valve 17 is raised from its seat and the auxiliary outlet is opened.

The casing 12 is provided with a leakage intercepting channel 23 formed in its inner with the port openings, (see Fig. 2)d and isV preferably formed with a downward inclination toward its ends. Aycoinplementary leakage diverting channel 24 is termed in the core 4, being positioned approximately opposite to the port openings 8 and 9 and vextending partially around the periphery of the core, preferably with a downward inclination Vfrom its ends. The leakage diverting'channels 28 and 24 arepositioned in relation to each other so that when the port openings 8 and 9-are closed the extremities of the two channels are in overlapping relation, forming a continuouspasage about the core and opening into the chamber 15. It will here be obvious `that vany leakage occurring iroin the inlet passage port between the core and its casing, will be inter-l cepted by the channels 23 and 24 and diverted into the chamber 15 from which it freely escapes through the open auxiliary outlet 16. Vhen the ports 8 and 9 are in communication through the chambery 15, the auxiliary outlet 16 is closed.

I claim as my invention:

1. A device of the class described, com-` prising a core having an inlet passage and an outlet pasage, said passages communieating respectively with apair of spaced lateral ports'in said core, said core having also a peripheral channel extending partially around said core approximately opposite oi' said ports, land a casing laterally enclosing said core in rotatable relation and normally closing said ports, sai-d casing having a lateral chamber opening toward said core and adapted to be moved by the operation oi' said casing into simultaneous communication with said ports, said casing having also an inner peripheral channel extending partially around said casing approximately opposite of said chamber, said channelsbeing positioned for inter-communication' when said ports are closed to form a continuous passage between and spaced from said ports and opening into said chamber.

y2. A device of the class described, comprising a core having an inlet passage and an outlet passage, said passages communieating respectively with a pair of spaced lateral ports in said core, a casing laterally enclosing said core iii rotatable relation and normally closing said ports, said casing having a lateral chamber opening toward said core and adapted to be moved bythe operation ot said casing into simultaneous communication withv said ports, 'said casing having an auxiliary outlet opening from said. chamber, a valve controlling said auxiliary outlet, and means Jfor opening said auxiliary valve when said ports are closed and for closing said auxiliary valve when said ports are in communication `with said chamber.
